I hadn't considered this - you may well be right. It depends on how Scott 
proposes to attack that particular problem, I will check with him.

More like:

EXCLUDED_PACKAGES += "broken1,broken2:These packages are broken by design and 
not supported;"
EXCLUDED_PACKAGES += "licenserequired,clickthru,special1:These packages 
require a special license agreement;"

The example syntax is horrible but you get the idea.

I think you meant to say "hear hear!" or maybe even "good show!"... ;)
